The B9114 follows Millgate and Millgate Loan in Arbroath. It is a short route, running roughly parallel to the A92 throughout, a route which it both starts and finishes on. There seems little reason behind this route being numbered, but due to its short, urban nature it is not marked on many maps, making it difficult to identify when it was first classified; if this is the original B9114 then it would date to around 1930.

The road starts on the A92 opposite Gayfield Park (Arbroath FC's ground) and heads north along Millgate Loan. To begin with the road passes modern housing estates and blocks of flats but soon turns into a side street in the old town centre. The B9095 comes in from the left along West Port (which is one-way towards us) and then our road becomes one-way as it continues along Millgate to end at traffic lights on the A92 relief road.

Before the A92 was given its present route the B9114 zigzagged right-left onto Brothock Bridge then crossed the square onto Commerce Street to end on the High Street, the original route of the A92.
